   - Be flexible enough to support unmanaged configuration outside the boilerplate that it manages
 
 Currently, the two kinds of boilerplate that are supported:
-- Node exporter rules and alerts for vms (number of hosts detected, cpu, ram, disks)
+- Node exporter rules and alerts for VMs (number of hosts detected, CPU, RAM, disks)
 - Terracd jobs metrics and alerts (to get the interval since the last plan/apply and a threshold value that will trigger an alert)
 
 # Inputs
 
 - **config**: This should be the value of the entrypoint **prometheus.yml** configuration file which will be generated from this value. The module will add some **rule_files** entries for the rule files it generates and otherwise will leave the content as is.
-- **fs_path**: Path where the prometheus configuration will be generated prior to synchronizting it with etcd. Beyond generating the **prometheus.yml** file there, boilerplate rule files will be generated in the **rules** subdirectory.
+- **fs_path**: Path where the prometheus configuration will be generated prior to synchronizing it with etcd. Beyond generating the **prometheus.yml** file there, boilerplate rule files will be generated in the **rules** subdirectory.

   - **expected_count**: Expected number of instances associated with the job

-  - **cpu_usage_threshold**: Maximum cpu usage as a percentage (ex: 90). An alert will be triggered if this threshold is crossed for 15 minutes of more.
-  - **expected_disks_count**: Expected number of disks (ex: 2). An alert will be triggered if the number of disks doesn't match. Can be set to -1 to disable the alert.
-  - **disk_space_usage_threshold**: Maximum disk space usage as a percentage (ex: 90). An alert will be triggered if this threshold is crossed for 15 minutes of more.

+  - **max_disks_count**: Maximum expected number of disks (e.g., 7). If both `min_disks_count` and `max_disks_count` are set, an alert will be triggered if the disk count falls outside the range.

   - **max_acceptable_latency**: Duration in seconds indicating the maximum acceptable response time for the service. If the service continuously takes longer than this to respond for an interval of time longer than **unavailability_tolerance**, a slow service alert will be triggered.
-  - **cert_renewal_window**: Delay in days indicating the expected renewal window for the tls certificate provided by the service. If the certificate the service provides expires within a delay shorter than this window, an alert will be triggered to indicate the certificate wasn't renewed properly.
-  - **has_tls**: Boolean indicating whether the service expects a tls connection. If false, alerts for the cert renewal window and tls version will not be set.
-  - **expect_recent_tls**: Boolean indicating whether the service is expected to use tls version 1.3. If set to true and the service uses a version of tls older than 1.3, an alert will be triggered.
